This invention relates" to'radiatorsand more particularly to the type of radiators used in building heaters, such as hot water and steam radiators.

Many radiators in use today are made of castiron in sectional form. sectionsusually have such a shape that they are difficult to cast and accordingly inai'i castings-must be rejected a-sbeingimperfect.

0 Further, most of the commonly used radiators have a comparatively small amount of heating surface in comparison to their size and weight and these are comparatively ex- I pensive.

15 The primary object of the present lnvll tion is toprovide a sectional radiator which is simple in construction, easy and cheap to manufacture, and which provides a construe tion that has a comparatively large heating 2'6 surface in comparison with its Weight.

Another object of the invention is to provide a simple and effective joint construction by which radiator sections are united.

With these and other objects in view the 25 invention consists in the improved radiator hereinafter described and particularly de= finned in the] claims.

The various features of the invention are illustrated in the-accompanying drawings, in which Fig. 1 is a vertical sectional view of a radiator embodying the preferred form of invention;

Fig. 2 is an end view of half of the radiator section looking at the right end of Fig. l.

The radiator illustrated in the drawings consists of a nest of frusto conical disks mounted between end closures with the entire structure being held by a single bolt passing through the end closures.

In making up the radiator two forms of frusto conical disks are used, which are referred to as inner and outer disks. The inner disks 10 consist of annular frusto 12 and a finished seat 14 adjacent the inner edge of the annulus. That portion of the disks 10 adjacent theseat 14 are reinforced to provide for the pressure to which the disk is submitted in making the The individual v conical disks having a finished outer edge.

joints-between the disksinthe radiator. outer disks 16 consist of annular frusto conica'l disks having a finished edge 18 at their inner portions or inner edge of the annulus and a finished seat 20 formed in mid portion of the disk. As shown in the drawings the finished edges 120i the inner disks have the same diameter as the seats 20in the outer, disks. The finished edges18' on the outer disks have the same diameter as" the finished) seats 14 on the inner disks. the disks" are assembled together as illustrated in the drawin s, the outer edge of one ofthe inner disks rests against' the seat of an adjacent outer disk and the inner edge of anouter disk restsa 'ainst the seat of an inner disk.

Two forms for end closures are provided. One end closure 22 has an outwardly extending flange 24 with its outer edge 26 finished to rest upon and have the same diameter as the seat 20 on an outer disk 16. Y The other end closure 28 has a seat" 30 formed at one end which has the same diameter as the inner finished edge 18 of one of the outerdisks and is arranged to cooperate with this seat in formingajoint'of the radiator. The end closures 22 and 28 are provided with threaded openings 32 and respectively by which a heating or cooling fluid may be circulated through the of disks for heating or cooling purposes.-

i It will be noted that the irnstoconical of the; inner and outer disk-s is such that when these disks are assembled a radiator the dis-ks meet each other in acute angle" and each individual pair of adjacentdisks provides a to gie joint such that when the disks are drawn together" the finished edges of one disk will bear upon a d: will be forced against the seat of adjacent disk with a pressure which will forma tight joint: Furthermore, the c more pressure brought; upon the to draw themtogether; the greater will be the pressure exerted upon the seat by the edges of adjacent disks. Due to the fact that a toggle joint is effected; a very slightmovement of the disks toward one another will exert an extremely high pres sure on the joint between the acl ae'entdisks.

To draw the disks togetherxin forming a 1 radiator, a bolt 36 is provided, having one end 38 threaded into a socket in the end closure 22 and another threaded end 40 passing through an opening 42 formed in the outer end of the end closure 28. A nut 44; is thread ed on the bolt 38 by which the pressure may be applied in drawing the disks together. Preferably the nut is operated by means of a socket wrench. A closure cap 46 is arranged to be threaded into-the end of the closure 28 to cover the nut after the radiator has been assembled.

It will be readily understood that the construction described above provides a comparatively simple and cheap piece of equipment by which to make radiators. The inner and outer disks are very simple castings to make and therefore there should be no rejects or discards. Furthermore, the seat and finished edge on each disk can be made in one operation on an automatic machine, so that the finishing of the disks ready for use in the manufacture of the radiator can be accomplished with a very cheap and simple operation. The finishing of the end closures can be accomplished as cheaply as the finishing of the disks. The toggle joint connection between the disks provides a construction by which the tight joints can be maintained with a very simple and cheap construction. The shape of the flanges on the outer disks 16' can be varied desired. As illustrated in the drawings these disks are circular. It is only necessary however that the seats and inner edges of the disks 16 shall be circular'or annular and the flange portion of the disk can be cut or shaped as desired in making various forms of radiator sections.

The preferred form of the invention having been thus described, what is claimed as new is: V

1. A radiator comprising innerand outer annular disks having a frusto conical shape arranged to be assembled together and meet one another at an angle to form a hollow structure, each disk having a finished edge and a finished seat so shaped that the edge of one disk will bear on the seat of an adjacent disk when the disks are nested, such that the direction of thrust of the disks edges under pressure against the seats is in a direct line and in continuation of the body of the disks against the seat, end closures for the disks, one closure having a finished edge and the other closure having a finished seat, means to bind the disks and closures together, and means to provide circulation of a heating fluid through the interior of the structure. a

2. A radiator comprising inner and outer annular disks arranged to be assembled together and meet one another at an angle to form a hollow structure, the inner disks having finished outer edges and finished seats ether and means to rovide for a circulation of the heating fiuid through the interior of the structure.

3. A radiator comprising inner and outer disks assembled together to meet one another at an acute angle to form a hollow structure, each disk having a finished edge accurately fitting a finished seat on the adjacent disk, an end closure at each end of the assembled disks and a bolt passing through the disks to the end closures to hold the disks in the nested position, the joints between the disks being such that the pressure of the bolt causes a toggle action by the movement oi the disks to apply pressure for tightly closing the joints betweenthe disks, and meansfor circulating a heating fluid through the interior of the structure.

4. A radiator comprising annular disks assembled together to meet one another at an acute angle to form a hollow structure, ea'ch disk having a finished edge accurately fitting a finished seat on the adjacent disk, such edges and their seats being so formed that the direction of thrust of an edge of a disk against a seat under pressure shall be in direct line and in continuation of the body of the disk pressing against the seat, end closures at each end ofthe nest, fluid connections mounted in each end closure, and a bolt passing through the disks to the end closure to hold the disks in nested position.
